This is the command-line that links libs/libcoolkeypk11.so.
It uses the compiler (g++) to link, which is good.
However, it uses -nostdlib and has a bunch of .o files with
"crt" in their names. I am not familiar with them. Sorry...
I would try removing those as well as -lstdc++ and -lgcc_s
from the command line.

I tried the following from the src/coolkey subdirectory:
touch .libs/libcoolkeypk11.so.exp
g++ -shared -Wl,-M -Wl,.libs/libcoolkeypk11.so.exp -o
.libs/libcoolkeypk11.so .libs/libcoolkeypk11_la-coolkey.o
.libs/libcoolkeypk11_la-dllmain.o .libs/libcoolkeypk11_la-locking.o
.libs/libcoolkeypk11_la-log.o .libs/libcoolkeypk11_la-machdep.o
.libs/libcoolkeypk11_la-object.o
.libs/libcoolkeypk11_la-PKCS11Exception.o .libs/libcoolkeypk11_la-slot.o
-Wl,-R -Wl,/usr/local/lib -Wl,-R -Wl,/usr/sfw/lib -L/usr/local/lib
-lckyapplet -ldl -lz -L/usr/lib -lm -lgcc_s
ldd on the resulting libcoolkeypk11.so shows:
reinholz@etrenank:~/Download/coolkey-1.1.0/src/coolkey$ ldd
.libs/libcoolkeypk11.so
libckyapplet.so.1 => /usr/local/lib/libckyapplet.so.1
libdl.so.1 => /lib/libdl.so.1
libz.so.1 => /lib/libz.so.1
libgcc_s.so.1 => /usr/lib/libgcc_s.so.1
libstdc++.so.6 => /usr/lib/libstdc++.so.6
libm.so.2 => /lib/libm.so.2
libc.so.1 => /lib/libc.so.1
ld reveals the same error I got when allowing gcc to build
libcoolkeypk11.so automatically:
reinholz@etrenank:~/Download/coolkey-1.1.0/src/coolkey$ ld
.libs/libcoolkeypk11.so
ld: warning: cannot find entry symbol _start; not setting start address
I'm not sure why gcc isn't detecting the proper crt* file
libcoolkeypk11.so needs to run...or maybe that's not the problem...
reinholz@etrenank:~/Download/coolkey-1.1.0/src/coolkey$ ld
/usr/sfw/lib/gcc/i386-pc-solaris2.11/3.4.3/crtbegin.o
ld: warning: cannot find entry symbol _start; defaulting to 000000000804807c
I get similar errors when pointing ld at crti.o and crtn.o installed in
/usr/lib
That makes me wonder if there's an issue with the _start symbol on the
OpenSolaris gcc3 and gcc-4.3.2 packages. (I reproduced the same errors
regardless of which version of gcc I used to build and link coolkey).
I'm at a loss...
